we have something similar in a custom snippet that checks for meeting the necessary criteria when clicking a button. we just added the “Run a Skuid JavaScript snippet” action type as an action that occurs before saving the model changes. But, I’m also looking to see if there is a better way to do this.
Also, i just found this page with a section called “Example: Validate required fields on Models, then navigate to another step”:
